If I use it before a public php function it won't work

e.g. public function instead of function.

You'll need to be more detailed.

when you type /** before a function, it works for me only half the time.

Show the snippet of code that doesn't work. Also some information like OS, version, etc, which you can get from the sublime text log (Menu > View > Show Console).

More detailed information can be extracted from the log by enabling command and input logging. open the console: sublime.log_commands(True); sublime.log_input(True);.
